Hi, if it's the same problem I was having its related to the dimesnions of the scene - when you change the height of the SceneGroup parent scene, it breaks the mechanics of the loop. Andrew Lahey helped me to fix it. We used a Render View to help - the scene that will be on air is 11520x180 pixels. That has a QUAD that has a size of 11520x 1080 with a Render View material that looks at the parent crawl scene. The parent crawl is also 1080 in height, make the parent scene 1080 pixels tall then the width the native resolution, the children can be 11520x180 pixels
Then just changing the Y position up a lot because the text plays at the bottom of the SceneGroup.
Hope to makes sense. I can send a scene if not
